Copy entire old drive to new drive, using SuperDuper (free) or Carbon Copy Cloner (not free).

Shutdown.

Put new drive in MBP.

Power up MBP.

Confirm it starts up and works from the new drive.

If you have a problem at any step of the above, identify exactly which step. If you've already done the steps as listed, identify exactly which step failed. The way I read your post, you only put the new drive in the MBP, and the old drive in the MBP and the case, but not the new drive in the case.

Now you have the freedom of time to discover why the old drive doesn't work in the case. A good start would be to post:
- exactly what case it is (manufacturer, model, any options)
- exactly what the new drive is (again: manufacturer, model)
- exactly what the old drive is (manufacturer, model)
- exactly which MBP model it is (post the Model Identifier from System Information.app)

It seems it must be the dock i was using.

Though the strangest part about it is that i could copy and access the new drive if i formatted it in the dock but if i formatted it in the pc it didn't read the drive.

I eventually got a Seagate dock and it seems to work perfectly without a hitch.

What would cause the one dock not to read the harddrive? Its the first time i have ever come accross this strange behaviour.
